Abstract

본 발명은 브라운관에 있어서의 소자회로에 관해 특히 직류전원을 이용하여 브라운관으 새도우마스크나 브라운관을 고정시키고 있는 구조물의 자기를 소개하여 전자비임이 미스랜딩되는 것을 방지하는 직류전원을 이용한 브라운관 소자회로에 관한 것으로, 텔레비젼이나 모니터에서 브라운관에 전자비임이 투사되는 상태에서 전원을 차단 후, 다시 전원을 투입하면 구조물의 쇠붙이가 자회되어 있기 때문에 전자총에서 발산된 전자비임이 소정의 형광면에 투사되지 않고 다른 형광면에 투사되는 미스랜딩이 발생하는데 이를 보정하기위한 것이 바로 소자회로이나 종래의 소자회로는 반드시 교류전원을 사용하는바, 예컨대 교류전원을 사용하지 않는 휴대용 엘시(LC)공진회로를 이용함으로써 직류전원전압을 갖는 회로에 소자기능을 제공함을 특징으로 하여 직류전원을 사용하는 휴대형 텔레비젼이나 계측기등의 브라운관을 소자시켜 전자비임이 미스랜딩되는 것을 방지하며, 정상상태에서 필요시 원격제어로 브라운관을 소자시킬 수 있어 교류전원을 사용했던 소자회로와 동일한 효과를 기대할 수 있으며, 또한 모노스테이블 멀티바이브레이터를 사용하였기 때문에 소자되는 시간을 쉽게 조정할 수 있다.The present invention relates to a device circuit in a CRT, particularly a CRT using a DC power supply to introduce a magnet of a shadow mask or a structure to which the CRT is fixed using a DC power supply to prevent the electron beam from being mislanded. When the power is turned off after the electron beam is projected onto the CRT on a TV or monitor, the metal beam of the structure is sublimed when the power is turned on again. Mislanding is projected on the device, and this is to correct the device circuit or the conventional device circuit by using an AC power supply. For example, by using a portable LC resonant circuit that does not use an AC power supply, It provides the device function to the circuit with It is designed to prevent CRTs from being mis-landed by using a CRT tube such as a portable TV or a measuring instrument that uses a DC power supply.The CRT tube can be elementally controlled by remote control if necessary in the normal state. The effect can be expected, and since the monostable multivibrator is used, the device time can be easily adjusted.
